FPS drops when things happen and stuff. And other stuff.

But really, your clock speed is not...impressive. You won't be able to run every game at full 60 FPS. Furthermore, besides your clock speed, you are running OSX which does not run Dolphin well, wheras the guy in the video most likely ran it on Windows or an Ubuntu release. It would probably be faster for you to run Dolphin via bootcamp
